Best Peanut Butter Shake

United Dairy Farmers

In this quickie mart's hodgepodge of stop-and-go goods, peanut-butter-and-chocolate lovers will find a frozen treat that's potentially habit-forming. Try it in any of three sizes -- 16-, 24-, or 32-ounce -- and settle on whether you want chocolate or regular milk. Then enjoy. It's like lapping up a Reese's Cup.
